Definitions
- the invention relates to a mixing blade for use on a device for mixing, wherein the mixing blade consists of a radially inner portion and a radially outer end piece, wherein the end piece is detachable and at least immediately adjacent to the inner portion substantially the same cross section has like this radially inner portion of the mixing blade.
- the invention also relates to a device for mixing, in particular of granular, abrasive materials, with at least one rotor shaft and with mixing blades.
- Mixers are known from the prior art with one or more mixer shafts arranged perpendicular to the mixing container bottom and arranged with mixing blades arranged in several planes and extending radially.
- the mixing blades have a preferably rechteckig cross-section with a wedge-shaped taper or knife-like chamfer in the forward direction to impart the Aufrungsgut in the penetration of an axial flow.
- the chamfer is directed upwards, the material to be treated is loosened, while it is compressed when the chamfer is downwards.
- the mixing blade body is made in one piece and is made of relatively soft material such as e.g. Made of mild steel.
- the hardfacing preferably applied by surfacing, may consist of a hard and wear-resistant coating, e.g. a tungsten carbide-containing alloy or a hard metal.
- the local thickness of the armor is adapted to the local mixing forces acting on the mixing blade.
- Multi-part mixer blades in particular bottom blades for concrete mixers, having a detachable blade nose are already known from the prior art, which are fastened to a support arm projecting radially from a mixer shaft and extending over a large part of the length of the mixer blades.
- releasably connected wearing bodies of mixing elements in mixing devices are also known with a carrier body.
- mixing devices for.
- asphalt mixers known in which the mixing elements consist essentially of hammerhead-shaped end pieces which are attached to radially projecting from a horizontal mixer shaft round support arms with screws.
- mixing devices to which the present invention pertains, two different aspects are essential and should be noted at the same time.
- the mixing tools are subject to considerable wear, which can be very different over the length of a mixing blade.
- an optimum mixing of the given materials should be achieved in the shortest possible time.
- the mixing vanes must be optimized in terms of flow.
- the actual mixing blades extending radially into the mix into extending support arms are generally disturbing and obstructive.
- the mixing blades are subject to wear by the material flows flowing at different speeds. They are subject to high and above all over the length of the wing varying wear. They preferably wear at their outer end due to the prevailing there highest peripheral speed.
- the wear protection applied to the ends of the mixing blades is worn, the underlying soft material underneath is easily removed and washed out.
- the mixing blade shortens after removal of the wear protection over-proportionally fast, with the resulting leaching even whole parts of the wear protection and the body break out which may result in damage to the mixer or downstream machinery, or at least an interruption of service.
- either the mixing blades attached individually or in groups to the shaft or even the complete shafts with the mixing blades welded thereto must be replaced at regular intervals, even if only the outer ends of the mixing blades except for the base material are removed and the wear protection on the leading outer edges is still strong enough.
- the mixing blade according to the invention has to Beilspiel a substantially rectangular cross section with one or two knife-like chamfers and an end piece which is releasably connected to the clamped in the mixer shaft part of the mixing blade.
- the contour of the detachable end piece corresponds substantially to the contour of the base body or the radially inner portion of the mixing blade at its transition to the tail.
- the cross section of the mixing blade is measured substantially perpendicular to a pointing in the direction of the mixing blade radius vector of the rotor
- the mixing blade extends from a near the shaft of the area lying to its end (including the tail) with a desired, predetermined profile without additional disturbing support arms.
- any support arms which are attached directly to the rotor shaft, either very short compared to the radial extent of the mixing blades, or the support arms are included or integrated in the overlap region with the mixing blade in the profile.
- the individually replaceable end pieces due to the preferred wear on these end pieces, significant cost advantages in terms of wear and maintenance costs can be achieved. Because of the same contour at the transition from the radially inner portion to the radially outer end In this case, the mixing properties of the device are identical to those of a corresponding device which has one-piece mixing vanes. At the same time, however, the maintenance costs and the maintenance times are noticeably reduced, because with wear of the end pieces, it is no longer necessary to replace the complete mixing blades, but only their detachable end pieces. Since under these circumstances, the tails are replaced faster and more readily than complete mixing blades, on average, better mixing results are achieved, or the mixing processes on average shortened in time.
- the cross section of the mixing vanes has a continuous and preferably smooth transition between the base body (6) and the detachable end piece (7). Smooth "means here with a continuous gradient or derivative, ie without any kink at the transition point.
- the detachable end piece can be made particularly wear-resistant to increase the service life.
- the tail in comparison to the rest of the mixing blade both made of any more wear-resistant material such as an oxide ceramic or hard metal and be coated with another armor material.
- the tail can be provided with a much stronger partial armor or with a full armor.
- the invention thus achieves optimal, fast mixing results with excellent ease of maintenance and low maintenance costs because of the same-contour transition from the body to the tail in combination.
- the connection between the end piece and main body of the mixing blade also very fast and easily detachable and recoverable and yet safe and stable.
- FIG. 1 shows a mixer 1, which in the preferred embodiment is provided with a rotating mixing container 2, consisting of a round, flat mixer bottom 3 and a cylindrical mixer wall 4.
- the mixer further has an eccentric to the mixing vessel center arranged, overhung reaching just above the mixer bottom rotor 5, which carries a plurality of planes arranged in radially extending mixing blades 6 with detachable end piece 7.
- the mixing container 2 and the rotor 5 are rotated by drives (not shown) in rotation.
- the cylindrical wall 4 and the mixer bottom 3 are stripped off by a stationary, combined wall bottom tool 8.
- the rotor 5 consists of a polygonal shaft (not shown) on which a plurality of tool holder 10 are arranged one above the other displaced. In the grooves 11 of the tool holder, the mixing blades 6 are mounted in pins (not shown) by means of the bore 13. The column of tool holders 10 with mixing blades 6 is clamped by a suitable releasable connection for operation.
- the mixing blade 6 and the end piece 7 consists of a preferably rectangular base body with a knife-like bevel 12. With the help of the bore 13, the mixing blades 6 are suspended with end piece 7 in the tool holder 10.
- the end piece 7 and the mixing blade 6 are formed as separate components. As shown in Figure 2 to 8 illustrate in plan view, the components at the junction by a suitable attachment releasably connected to each other. The compound must be able to transmit the forces acting on the tail 7 mixing forces on the mixing blade 6. In addition, the end piece 7 must be secured against rotation with respect to the remaining mixing blade 6.
- the detachable connection and securing against rotation can be achieved by various variants (FIGS. 2-8), for example by an overlap of end piece and mixing blade (FIGS. 3, 6), by one or more centering pins (FIG. 2), two or three Several screws (Fig. 7), a positive, polygonal pin-socket connection with axial screw (Fig. 4) or via a laterally bolted metal strip (Fig. 8) take place.
- the screw 14 is sunk as deep as possible in the end piece 7 and the counterbore 18 closed by a suitable, removable again filling 19.
- the bore 16 is preferably provided with a thread whose diameter is greater than the thread diameter 17 in the mixing blade 6.
- the threaded hole 16 can be used in the disassembly of the tail 7 of mixing blades 6 by using a pressure screw for pulling the tail 7 of the pins 15.
- the components 6, 7 overlap at the connection point.
- the main body of the end piece 7 and the mixing blade 6 are provided with a wear-resistant coating 20.
- the connection takes place from the trailing outer edge of the components 6, 7.
- Figure 4 and Figure 5, section along the line A-A ', show a variant in which the connection between the components 6, 7 via a positive pin-socket connection 23, 24 takes place, wherein the pin and the socket with a polygonal profile is provided, which prevents rotation of the pin 23 in the socket 24.
- the pin-and-socket connection is achieved via a suitable attachment, e.g. a screw in the axial direction 25, releasably connected to each other.
- the dividing line between mixing blade 6 and end piece 7 can be located at any point.
- Variable is also the geometry and arrangement of the connecting surfaces, the attachment and the rotation.
- FIG. 6 shows a variant in which the end piece 7 overlaps with the mixing blade 6 and the fastening takes place by means of a screw connection 26 in the axial direction.
- FIG. 7 shows a variant of FIG. 1 in which the fastening and the anti-twist protection take place in the axial direction by a plurality of screws 27.
- FIG. 8 The embodiment of the end piece 7 with a threaded pin 28 is shown in FIG. 8. Securing against rotation of the end piece 7 takes place, for example, via a sheet metal strip 29 with bores 30 and screw connections 31 on the trailing outer edge of the components 6, 7.
- Figure 9 and Figure 10, section along the line A-A ', show a variant of Figure 2, in which both the mixing blade 6 and the end piece 7 have two blade-like bevels 12, 32, 33.
- Preferably, only the mixing blade 6 has two wear-protected knife-like chamfers 12, 32. Since the wear is preferably in the forward direction and the end piece 7, both the mixing blade 6 by 180 ° rotation in the grooves 11 of the tool holder 10 and the end piece 7 by appropriate rotation continue to be used until the wear protection on the bevels 12 and 32 and 33 is completely worn.
